Q: Is this the price for both the thermostat and the reciever together?
A: Yes it is.
Q: We have a shared office two separate floors without access to each other sharing one boiler. We have a Hortsmann HRFS1 in the ground floor and working. Would it be possible to add a second so the first floor so the other occupier could increase the boiler operation times if they were working late etc?
A: Yes, as long as you have the suitable zone valves to separate out the flow to the two floors.
Q: I need to change the batteries in the controller but I don’t understand the manual!? Can someone help. Where is the reset button?
A: Give support a call on 01179 788 773. They will talk you through it.
Q: how do i turn off the rf programmable room stat when i go on holliday?
A: Just press the FROST button.
Q: Recently purchased this thermostat. I think my unit is working the opposite way it should. When I move the set point temp below the room temp the heating comes on and when I turn it up it goes off. I know it can be used as a cooler but reading the manual I’m sure I’ve made the adjustments so as it’s working as a heater. Can you help
A: If the light on the receiver is on when the heating is off (and vice versa), then the receiver is wired wrong (wired to SL off instead of SL on).
Q: can I change the frost protection temperature setting from 5 degrees to 15 degrees
A: It cannot be changed.
Q: I have a horstmann thermostat and controller fitted to my combi boiler similar to this one. They both work fine but the display on the thermostat is faulty. Can I purchase this ( understand I need to purchase both items) and pair the new thermostat with the existing controller wired to the boiler.
A: Yes you can.
Q: We have recently moved into our property, it has an HRFS1 installed.
1, Where is the receiver likely to be located ?
2, How do I access the DIP switches on the transmitter and receiver ?
A: If you have a combi boiler, then it will normally be installed next to the boiler.
If you have a traditional system with a hot water cylinder, then it will normally be in the airing cupboard.
You will need to remove the cover to access the DIP switch. For the receiver you will need to switch off the electric before you do.
Q: Can you please help me, I don’t know how to switch on my heaters with horstmann
Can you send me please some instructions
Thank you Floriana
A: A manual is available under the downloads tab.
Q: Hi there I want to have no timer settings and just use the thermostat manually and turn up and down when I want but I can't see to work out how to do this please can someone help
A: Hi. I'm afraid this thermostat doesn't have a manual mode. I can only suggest setting all the time/temperature programs to happen early in the morning, then you can use the temporary over ride during the day.
Q: How do I link them together
A: There are DIP switches on both thermostat and receiver. You must make sure they are set the same.
I understand that you set the temperature with this thermostat and not an on off time period.
However I am confused by the 5 programme settings. Does each programme run for a specific period of time eg 1 hour?
I want to have the heating on from 6am to 7am and then from 6pm to 10pm at 19* every day. Can you advise how I should programme each of the 5 daily programmes to achieve this please.
Many thanks for your time.
A: It runs until the next setting.
1) 6am 21C
2) 7am 5C
3) 6pm 21C
4) 10pm 5C
5) 10pm 5C
Q: Does th hrsf1 come with a stand for freestanding on a shelf etc .
A: Yes it does.
Q: Can you please send me by email the instructions to the thermostat above T50 which I bought, as I have lost the instructions. Many thanks, B Butcher
A: You can download it from the "Downloads" tab.
How do i adjust the temperature on the thermostat,
I couldn't understand it on the manual
A: To adjust it temporarily, just use the up arrow button. It will go back to programmed setting on the next time/temperature change (or you can use SET button to cancel it).
Q: Please can you tell me if there is a manual override setting which is constant?
A: I'm afraid not.
Q: how do I know when my heater is working. doers the unit show any displays to show it is working? thank you
A: There is a symbol on the display, and a LED light on the receiver, when the heating is on.
Q: Is the HRFS1 a direct replacement for a Horstmann CS17, that is to say will it fit on the CS17 base without any wiring changes?
A: I'm afraid not.
Q: Could you please tell me how to change the time.
I would be very grateful.
A: Please see pages 16 and 17 of the manual (downloads tab).
Q: I currently have this controller installed on my boiler. The numbers (temperature figures) are starting to disappear, what do I do. If I need to replace the unit can I just replace the display box on the wall or do I have to also change the box attached to the boiler.
A: Try changing the batteries. If that doesn't help, then you will probably need to change it.
Although they are only sold as pairs, you can set the new controller to work with your existing receiver.
Q: Can you please tell me how to do a reset...we have inherited one with settings all over the place ..its so complicated to reprogramme ...its beaten us after 2 days of trying
A: There is a reset button on the bottom left. You will need a pin or similar to press it.
Q: Is it possible to programme both a START and a FINISH time for each day?
A: You programme temperatures instead of on and offs, so you could programme (for example) 20C in the morning and 5C in the evening.
Q: Hi if it's not possible to turn this ch programmer off (off mode) how do I turn it off in summer?
A: You use the frost protection mode in the Summer.
Q: the last tennants have disposed the instructions !and i dont know how to use it
A: You can download it from the downloads tab.
Q: Is there a way to completely disable the programmes on this thing? Mine has several times set from previous owners all I can do is edit the programmes but want to turn it off and use it just when I want to by setting the temperature. Thanks.
A: I'm afraid it doesn't have a manual mode.
Is it possible to use 2 thermostat on 1 receiver?
Also, could you kindly please point me to where I can download these instructions to attach an additional thermostat as my plumber/installer has disposed of the manuals etc.
A: I'm afraid not. The receiver will listen to only one thermostat. You will need to install a second receiver.
Q: I have this product but the wireless controller is broken, if I get a replacement controller will it sync automatically?
A: You will need to change the address code switches on the new one to match the old one. They will then work together.
Details are included in the installation manual.
Q: I have an existing HRFS1 programmable room stat controlling my heating but I am hoping I can add another receiver paired to my existing thermostat to control some underfloor heating as well, would 1 thermostat control 2 receivers? And if so can I buy an additional HRFS1 receiver?
A: It will control multiple receivers, but they are not available separately.
Q: Can this be used on a boiler with a hot water tank?
A: As long as there is 2 x 2-Port or 1 x 3-Port motorised valves.
This will not control hot water, a separate control is needed for hot water.
Q: Is this stable to control a 2.75 kw electric radiator?
A: Yes it is.
Q: Can two separate stats be used within the same building to control two separate zones within the building
A: Yes they can.
Q: Good morning,
I have a Horstmann RF programmable room thermostat with the number inside the receiver T50. could you please tell me if the HRFS1 ( which looks the same ) is the replacement and I do not have to change the wiring inside the receiver.
Many thanks for your time
A: I'm afraid that is not the model number. Please email us a photo to email@example.com and we will identify it.
Q: Hi, can the controller be purchased on it's own?
A: I'm afraid not.
Can the receiver be purchased on its own?
A: I'm afraid it is only available as a pair.
